Front

What is the measure of angle D if m∠D = 64°?

Back

m∠D = 64° is the correct answer.

Front

What is the slope-intercept form of a line parallel to y = 4x + 3 that passes through (2,5)?

Back

The equation is y = 4x - 3.

Front

How do you find the midpoint between two points (-4,4) and (-2,2)?

Back

Midpoint = ((-4 + -2)/2, (4 + 2)/2) = (-3, 3).

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

How can you determine if two lines are parallel from their equations?

Back

Two lines are parallel if they have the same slope.

Front

What is the equation of a line in slope-intercept form?

Back

The equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of the line given by the equation 2x + 5y = 10?

Back

Rearranging gives y = -rac{2}{5}x + 2, so the slope is -rac{2}{5}.

Front

What is the relationship between the slopes of two perpendicular lines?

Back

The slopes are negative reciprocals of each other.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope = (y2 - y1) / (x2 - x1).

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).
